I think Myosmith solution sounds good and the only thing I can think of if that don’t work is that your lock was the type that lets you pick the number. They have a ring that lets you turn the numbers with the lock open, the lock comes set to 0000. if with it not fully in the slot I'm not sure but that ring could be turned to let the number change. I would have to look at mine and see if that’s possible. Hopefully his fix works.
